Nils: I'm the Teamcaptain
and the head of almost 50 team members of Raceyard
and we are going to build
a racecar this year.
To turn our group into a team
we decided to stay 3 days in Brahmsee
to get to know each other.
Pretty early in the season
we were able to form
a highly motivated team.
The team spirit helped a lot
to build a working
and efficient car this season.
Julius: I'm the head of the non-constructive department.
Compared to the other departments
we have the highest portion of women in this department.
In my opinion, Raceyard never had
such a good public relations work
in the history of raceyard,
as they have now.
Dennis: Regarding to last year we could save
material to create a lighter frame.
We use the same material, steel
and the design is pretty much the same.
The pedal system design was
- regarding to the solidness -
improved by FEM data analysis.
We could design a way
more solid pedal system.
The design of the pedals is more solid
to avoid plastic distortion.
The steering wheel is this year
coated with 2 carbon fibre layers in sandwich-fabrication and through this
fabrication we save a lot of weight. :)
Michel: The difference between a regular car seat
and a racing seat is huge.
there is no upholstery or big plastic parts.
This would be to heavy.
Instead of using plastic- or metal plates
it's made of all-glass fibre material.
At the beginning we create a positive imprint
made out of Styrodur,
grind that positive imprint
and laminate the seat by using
vacuum injection process.
Thomas: One of the goal was
to optimize the chassis supension
of the 2012 racecar.
We adapted the kinematic of the previous model
improved it, and
assigned it to the 2013 model
There were lot of thoughts how to archive a faster racecar
on the racetrack for the 2013 model.
Henning: Our design didn't change that much
from the previous season.
We designed a smaller gearing
with a higher transmission ratio.
The packaging is pretty much the same.
We use the same AC inverter
and also the same electric engines.
We were able to use the data from the previous season
to design a smaller cooling unit.
Maria: The bodyworks is one of the specialties
in this season for the racecar.
We don't use a 3D molding cutter this season.
We simply use the CNC lathe machine to make cuts
into the surface and fold the plastic material
Like origami folding technique.
But instead of paper we use
polypropylene-extrusion plates.
Mario: Besides improving accumulator safety issues
we focused on the maintainability of the accumulator battery.
Several parts of the accumulator containment were made by laser sintering fabrication.
Even though the design changed this season
The specifications of the battery stayed the same.
Delf: The accumulator consists of 96 cells
with its individual current, own temperature.
this sampled data needs to be monitored
by our battery management system.
This years battery management system is a complete self developed system.
We had serious problems with the battery management system last season,
it was very expensive, created a lot of trouble
and not very maintainable.
That was the reason why we built our own battery management system.
For the wiring we built a 1:1 frame out of PVC pipes
to avoid working on the steel frame.
In the phase of design the frame is claimed by the mechanical engineers
already enough and we wanted to avoid any interruption.
When we work on the steel frame no one else is able to work on the frame.
We also work on an improved driver-information system.
The driver can check all important information via the onboard dashboard
to display all relevant information
and the driver can setup
some parameter on its own.
Henning: We're done?
Niiiiiiiice...
